class | _Script_List |
Splits an argument passed to Knob::from_script() into an array of const char* words, allowing a parser to use the words as individual parts of the value of the knob. This encapsulates a common tcl function so that the scripting language can be replaced.
The inverse Knob::to_script() function should print the same words with spaces between them. If the words may have punctuation or spaces in them then you should use a cstring object to "quote" them. If the quote argument to to_script() is on you should also add a '{' before and a '}' after the list.
Knob::Script_List::Script_List | ( | const char * | arg | ) |
The constructor allocates any temporary storage, and splits the argument according to the scripting language's rules (at spaces for tcl). You can then get at the individual words as C string values. These values may be used as an argument to to_double(), or as an argument to a constructor to an internal Script_List to make a nested list.
Knob::Script_List::~Script_List | ( | ) |
The destructor frees the temporary storage for the split list.
|
inline |
Returns word n of the split list. n must between 0 and size()-1.
|
inline |
Returns the size of the array.
|
inline |
Returns true if the constructor encountered an error. If so the only legal operation on the list is to delete it. Knob::error() will have been called to print an appropriate message.
